WIRING
This section contains the input, output and serial communications wiring information for the CX–1010.
Please read this section prior to wiring the CX–1010 to ensure that you make the appropriate wiring
decisions.
NOTE: The installation of this motor control must conform to area and local electrical codes. See The
National Electrical Code (NEC,) Article 430 published by the National Fire Protection Association,
or The Canadian Electrical Code (CEC). Use local codes as applicable
Use a minimum wire gauge of 18 AWG.
Use shielded cable to minimize equipment malfunctions from electrical noise and terminate the
shields at the receiving end only.
Keep the AC power wiring (J4) physically separated from all other wiring on the CX–1010. Failure
to do so could result in additional electrical noise and cause the CX–1010 to malfunction.
Inductive coils on relay, contactors, solenoids that are on the same AC power line or housed in the
same enclosure should be suppressed with an RC network across the coil.
A hand operated supply disconnect device must be installed in the final application. The primary
disconnect device must meet EN requirements.
Install an AC line filter or isolation transformer to reduce excessive EMI noise, such as line notches
or spikes, on the AC power line.
